Sainte-Croix Airport

Economic and private business reasons. The airport was a privately owned field, reportedly associated with the large adjacent industrial foundry, Bibby-Ste-Croix. The closure was likely a business decision by the landowner, who repurposed the valuable land for industrial activities, such as storage and potential future expansion, thereby eliminating the costs, maintenance, and liability of operating an aerodrome.

The airport is permanently closed and has been repurposed for industrial use. While the physical asphalt runway, taxiway, and a hangar building are still visible, the site is now used as an open-air storage and staging area for the adjacent Bibby-Ste-Croix foundry. Satellite imagery shows the former apron and parts of the runway covered with industrial materials, large pipes, shipping containers, and trailers. The runway is no longer maintained for aviation and is not marked as active.

Sainte-Croix Airport was a private aerodrome that served the general and corporate aviation community. Its primary identifier was CSX3 (the ICAO code CA-0359 is a non-official identifier used by some third-party databases). It featured a single paved runway (07/25) measuring 3000 by 75 feet, which was capable of handling a wide range of general aviation aircraft, from single-engine piston planes to light twin-engine aircraft and some smaller corporate jets. Its main operational purpose was likely to facilitate business travel for the executives and clients of the Bibby-Ste-Croix foundry and other local enterprises, as well as serving local private pilots.

There are no known plans or prospects for reopening Sainte-Croix Airport. The land is now fully integrated into the ground operations of the industrial facility that owns it. Given the conversion to industrial storage and the significant cost and regulatory hurdles required to re-certify a closed airport, a return to aviation service is considered highly improbable.
